Consider a laminar boundary layer developing over an isothermal flat plate. The flow is incompressible, and viscous dissipation is negligible. (a) Substitute Equations 6.31 and 6.33 into Equation 6.39 to determine the thermal boundary conditions in dimensional form associated with flow over a flat plate of length L and temperature Ts. (b) Substitute Equations 6.31, 6.32, and 6.33, as well as the definitions of ReL and Pr, into Equation 6.36, and compare the resulting dimensional expression with Equation 6.29.
